PERFORATING AND TRIMMING MECHANISM FOR FOLDING-MACHINES.

Specification of Letters Patent.

Patented Jan. 28, 1913.

Application filed November 3, 1911. Serial No. 658,344.

To all whom it may concern:

Be it known that I, CHARLES O. L. CAR- DELL, a citizen of the UnitedStates, and resident of Pearl River, county of- Rockland, State of NewYork, have invented new and useful Improvements in Perforating andTrimming Mechanism for Folding-Machines, of which the following is aspecification.

The main purpose of the present invention is to produce a perforatingand trimming mechanism for folding machines which will be moreconvenient to adjust and move into and out of operative position. Thesemechanisms, as usually constructed, are placed in inconvenient positionsupon the ,machine so that the operator is compelled to reach intoinconvenient places for setting them into or .out of operativepositions.

In order that the invention may be fully understood I will firstdescribe the same with reference to the accompanying drawing andafterward point out the novelty in the annexed claims.

In said drawing Figure l is a detail sectional side elevation of myimproved perforating and trimming device applied to a folding couple.Fig. 2 is a detail plan view of the same. Fig. 3 is a detail frontelevation of the main parts of the same.

The drawing shows only sufficient of a paper folding machine toillustrate the invention.

1 is part of the frame of the folder in which a air of folding rollers 5and 6 are journaled at their ends. These rollers are geared together asshown at 7 and 8 in the usual manner. operates with the rollers isomitted since it formsno part of the present invention.

10 is a rock shaft journaled at its opposite ends. in the side frames ofthe machine and centrally braced by hearing bracket 11, mounted upon across bar 12 of the machine frame. This rock shaft 10 has adjustablysecuredto it at 15 and 16 the rock arms 17 and 18, formed at their freeends with bearing sleeves 19 in which is journaled a rotary shaft 20.The shaft 20 has a serrated perforating cutter 21, secured to it at itsinner end in the usual manner and a trimming cutter 22, secured to itadjacent to its outer end also in the usual manner. The perforatingcutter 21 operates against the periphery of one of the folding rollers5,

The folding blade which co' while the trimming cutter 22 operatesagainst the usual trimming collar 23 adustably secured upon the shaft ofthe foldmg roller 5.

The outer end of the shaft 20 carries a p1n1on 25 which is adapted tomesh with the gear or pinion 7 The outer end of the rock shaft 10carries a controlling rock arm 30 whlch is adjustably secured to it bymeans of a set screw 31. This controlling rock arm 30 is formed with ahandle 32 and with a transverse curved slot 33. A set bolt 35 passesthrough the slot 33 and is threaded into the side frame 'of the machine.

It will be observed that the controlling hand lever 30 is presented atthe outside of the machine in convenient osition for operation. Byloosening the olt 35 the o erator can shift the lever 30 for moving theperforating and trimming cutters 21 and 22 into and out of operativeposition. The arrangement of this lever afiords convenient means foraccurately setting the cutters with reference to the folding rollers,and avoids the necessity of getting under the machine for effecting thenecessary adjustments.

What I claim is:

1. In a folding machine, the combination of suitable folding rollers,with a rotary cutter cooperating with one of said rollers, a rockingframe supporting said rotary cutter, an operating handle mounted uponsaid rocking frame and presented at the outside of the folding machine,-and means for securing said handle in the desired adjusted position.

2. In a folding machine, the combination of a suitable frame, foldingrollers mounted in said frame, a rock shaft journaled in said frameadjacent to said rollers, rock arms moun ted upon said rock shaft, arotary cutter shaft journaled in said rock arms, perforating andtrimming cutters mounted upon said rotary shaft, in operative relationto one of said rollers, and an operating lever secured to the outer endof said rock shaft on the outside of the machine frame.

3. In afolding machine, the combination of the machine frame and thefolding rollers journaled therein, with a rock shaft suitably journaledin said frame, rock arms mounted upon said rock shaft, a rotary shaftjournaled in said rock arms, a rotary cutter mounted upon said rotaryshaft, means for driving said rotary shaft, a controlling hand leversecured to the outer end of said rock shaft upon the outside of themachine frame and means for securing said controlling hand lever in thedesired adjusted position.

4:. In a folding machine, the combination of a suitable frame and gearedfolding rollers journaled in said frame,.with a rock shaft journaled insaid frame and carrying rock arms, a rotary shaft journaled in said rockarms, a perforating cutter and a trimming cutter, both mounted upon saidrotary engaging said controlling hand lever for securing it in thedesired adjusted position.
